I am having a problem with the final step of actually switching the bits. I can't find a way, a bitwise action, that will allow me to flip only the specific bit and keep the rest of the number the same. WebMay 5, 2010 · Just as with decimal longhand division, the digits of the dividend are considered from most significant to least significant, one digit at a time. This is easily accomplished by a left shift in binary division. Also, quotient bits are gathered by left shifting the current quotient bits by one position, then appending the new quotient bit. phn toowoombaWebThe Bitwise operators are used to perform operations a bit-level or to manipulate bits in different ways.
